Area of Science:

  • Neuroscience
  • Machine Learning
  • Biomedical Engineering

Background:

  • Deep learning models for motor imagery (MI) electroencephalogram (EEG) decoding struggle with cross-session generalization and channel-level interpretability.
  • These limitations impede the real-world use of MI-EEG brain-computer interfaces.

Purpose of the Study:

  • To introduce DO-PI-EATCNet, a novel deep learning framework designed to enhance generalization and interpretability in MI-EEG classification.
  • To improve the practical applicability of MI-EEG systems.

Main Methods:

  • DO-PI-EATCNet employs distinct modules for feature representation, temporal channel modeling, temporal regularization, and channel compactness.
  • Key components include Latent-Projected Attention (LPA) for spatiotemporal discriminability, Temporal Channel Cascaded Collaborative Attention (TCCA) for dependency refinement, and Fractional-Order Difference Temporal Consistency Loss (FD-TCL) for temporal stability.
  • The Multi-Population Dream Optimization Algorithm (MPDOA) is utilized for efficient channel selection.

Main Results:

  • The compact DO-PI-EATCNet model achieved 84.4% accuracy and a Cohen's κ of 0.790 on the BCI Competition IV-2a dataset under a within-subject cross-session protocol.
  • MPDOA reduced the number of EEG channels from 22 to approximately 15 and decreased computational load (MACs) by 27%, with a minimal accuracy drop from 84.9% to 84.4%.
  • Selected channels demonstrated anatomical plausibility, primarily located over sensorimotor regions, supported by scalp topography visualizations.

Conclusions:

  • DO-PI-EATCNet effectively addresses generalization and interpretability challenges in MI-EEG decoding.
  • The proposed model offers a balance between classification performance, computational efficiency, and physiological interpretability.
  • The findings suggest DO-PI-EATCNet is a promising advancement for practical brain-computer interface applications.
